I've noticed my TPS are a good 3psi off vs a good tire Guage. Is this the same for you guys? I have all my tires at 35-36 but the dash shows 32-33psi.

Set mine all to 33 the day I brought it home. The dash reads 33 for 3 of them, and 32 or 33 for the 4th. Guess I got that one closer to 32.5. Either way, it seems ok to me.

I think it varies. I kept my tires at the required pressure according to the tpms gauge and the first set wore out on the outer edges first - so probably a few psi low. Now I still go by the tpms but add 3 psi.

two of mine are right on and two of mine are off by 1 psi according to two digital gauges I have, that both match each other.

this is probably the reason the manual specifically states not to use the TMPS as a tire guage. RTFM
